To fully appreciate Moustapha’s text, one must understand the fundamental engineering distinctions between axial and radial turbines.
Axial turbines are commonly used in large-scale power generation, such as in steam and gas turbines. The design of axial turbines involves a rotor with multiple blades attached to a central shaft. The stator, which is stationary, directs the fluid flow onto the rotor blades, producing a torque that drives the shaft.
Moustapha categorizes losses into:
Turbines are mechanical devices that extract energy from a fluid flow and convert it into useful work. This work is typically used to drive a compressor, an electric generator, or a propeller. Based on the direction of fluid flow relative to the axis of rotation, turbines are broadly classified into two main types: axial and radial.

The book you are referring to is likely by Hany Moustapha , Mark Zelesky, et al., published by Concepts NREC (a leading turbomachinery software and education company).
Hany Moustapha’s "Axial and Radial Turbines" (2003) is a definitive 358-page textbook outlining aerodynamic and structural design principles for both turbine types. The work details performance parameters, showing radial turbines are superior for low-flow, high-pressure applications while axial designs excel in large-scale operations.
